ROOFING.

Application led October 4, 1926. Serial No. 139,291.

My present invention relates .to improvements in roofing and has special reference to the provision of an artlculated roofing 1n -which separate weather resisting elements,

similar to or corresponding with tiles, are secured together and reinforced 1n such a I way as to permit of their being secured in usual terra cotta or burnt tile.

' present invention.

final position in groups and so that they will have the requisite substantiality to sustain the service required of them whilethe 1nd1- vidual elements and the structure as a whole can be made of much more economical and lighter materials.

As is well known, tiles, and particularly the variety of tile called Spanish tile, which have a curved or undulating surface, are popular not only on account of their weather resisting properties, but also because of their appearance. Such tiles, however, are both heavy and comparatively brittle. It is necessary, because of the brittle nature of the material @f which they are formed, to give them a relatively heavy body, which entails 'a relatively heavy product. And a relatively heavy roof structure mustV be provided for the support of the Andl even the ordinary burnt tile, notwithstanding 1ts weight, is not infrequently broken and requires replacing.

As will hereafter be seen, the separate weather resisting elements of my structure may be made of relatively light material such as fabricor tissue or felting impregnated with asphaltum, a cement mixture or other cementitious material into the .outer surface of which may be impressed granite or stone or mica Hakes as is not an uncommon practice. The units so formed, as will hereafter be seen, are articulated or secured together so as to reinforce the individual' units and secure an assembly between them which is much more substantial and depend'- able than the assembly at present attained between the individual tiles of a tile roofas it is now made. o

In order to attain the foregoing objects I have provided a structure illustrated in thev accompanying drawing inwhich-d Fig. 1 is a plan of a section of art1ulated roofing constructed in accordance with m Fig. 2 is an end elevation of the structure shown in Fig. 1.

3 is a plan of a section of frame work jA upon which the tiles or covering. elements sway departing are to 4be mounted showing in dotted lines the Lrelation of such a section to adjacent sections, and Q, y F1g. 4 is an end view of the structure shown in Fig. 3. y

I haveemployed similar reference characters to designate similar parts throughout the several views.

While I have illustrated my articulated roofing as provided in sections containing fifteen individual covering elements or tiles, 1t is obvious that either a larger or smaller number of covering elements or tiles could be grouped in a single section without in any from the principle of the structure herein described. Further, if temperature conditions permit it is preferable and feasibleto install my roofing upon the rafters of the roofing ofbuildings directly instead of covering suchlrafters first, as is now the general practice, with Isheathing'. For the assembly with the rafters 0f the roofing aforesaid I provide, in the size of construction illustrated and described, three lengths of material each designated by the character A. This 'material may be suitable pieces of wood-or metal, as may be deslred, and they are set preferably slightly .obliquely to the right lines of the struclines and designated by the character A.' v

Secured at equal intervals to the members A are transverse members B which Vstand up from the plane of the members A a distance slightly less than the depth of the hollow formed by the curved inner surface of the tile elements.- The memhers A and B may be secured together by nails or bolts or staplesg as shown, or in. any other desired way, it being understood that while a sturdy and dependable structure is desired, nevertheless the possibility of giving slightly Without breaking is highly desirable in all portions of a building and especially in the roofing. Secured along the tops of the members B are segmental elements C preferably moulded from Portland or other hydraulic cement and reinforced with aninsertion of fabric such as burlap vor reticulated or woven metal. The curvature of the top of the member C is such as to conform to and fit with the inner surface of the curved tile elements.

The curved tile elements D are preferably formed of fabric or tissue or felting impregnated with asphaltum or other suitable cementitious material, and as 'before stated, into the' outer surface of which may 4be impressed flakes of stone or mica as 1s the present general cures the individual tile elements together burnt tile and much more firmly than is the present practice in securing tiles to a roof and the central projecting portion of each tile element is so reinforced and supported as to be -able to withstand not only the service that is required of a roofing, but also has sufficient strength to receive, without injury, a'considerable blow and to support walking thereon as the unsupported edges of the tile elements are depressed and thereby Withdrawn from ordinary contact.

It will also be evident that my structure is milch lighter than a roofing formed of is not only not brittle, but is so -constructed that slight movement between the tile members or flexibility in the structure is easily possible without any impairment of the roofing.

By securing a number of the individual tile elements together in work may be factories where the means@ done most expeditiously and economically, considerable expense in installing the tile upon the roof of a building is saved. i

Having described my invention what llA claim as new and. desire to secure by 1. An articulated rooting comprising a and transverse base members disposed parallel with each other and obliquely with said supporting members secured to said supporting members. 4

2. An articulated roofing comprising base members, transversely disposed parallel supporting members secured to said base members, ca. s of reinforced concrete secured to sai supporting members, and a plurality of flexible curvilinear tile elements resting upon and an edge extending under laterally adjacent tile elements.

secured to said caps having 3. An articulated roofin comprising base members, transversely isposed parallel supporting members secured to said base members, a plurality of asphalt composi tion tile elements, andsconcrete members inserted between, conforming with, Vand se-v cured to said supporting and tile members.
